bad quarto
noun1
A quarto-sized publication of a play, especially a Shakespearean play, that is considered spurious by virtue of having been copied down during a performance or later reconstructed from memory.
- The implication is that theatrical practitioners have access to the “bad quarto” that is unmediated by the history of its scholarly reception; these practitioners can therefore be depended upon to discover in their performance of the text the true nature of its origin.1998, Laurie E.
